Equipped with washing line and train-washing machine in metro depot, the train-washing operation is one of the most frequent technical operations in metro depot. However, different kinds of washing line type and train-washing operation mode may influence directly the efficiency of train-washing operation. Firstly this paper introduces the typical arrangement types of washing line and the train-washing operation modes, and then this paper put forward a kind of pass-type washing line at throat area equipped with bidirectional train-washing machine, with which not only the length of throat area can be reduced, the efficiency of train-washing operation can be increased, but also the flexibility of train-washing operation can be improved.%地铁车辆基地内配置有洗车线和洗车机设备,洗车作业是地铁车辆基地内最为频繁的工艺工作之一.不同的洗车线布置形式和洗车作业模式,对洗车作业的效率有着直接的影响.首先介绍典型的洗车线布置形式和洗车作业模式,然后提出一种配备双向洗车机的咽喉区通过式洗车线,其缩短了咽喉区长度,提高了洗车作业的效率,也增强了洗车作业的灵活性.
